Hamlet 's tragic flaw is his inability to kill Claudius when the chance was there. He delayed Claudius death too many time in which ultimately caused the deaths of, his mother, Ophelia, Laertes, and himself. Hamlet could’ve killed Claudius but he decided to doubt himself and delay his death. Hamlet had a point where he thinks if he should “to be or not to be,” (III.i.64). He was thinking about if he should just kill himself or if he should continue through with killing Claudius. He looks at both options all the way, if he kills himself he is scared “for in that sleep of death what dreams may come” (III.i.74), and if he lives he would still have to still claudius. He is scared because he doesn 't know what will happen to him if he dies.
